I bought a 2013 Taco Double Cab v6 and I'm in the process of trying to find a simple way to make her breath easier. I'm not planning on Off roading or pressing the pedal to the metal on this taco . K&N claims this filter increases HP. Would you be kind to share your experiences with it, the pros/cons of this filter, and whether or not it is worth the money? Thanks in advance for any feedback.

It does not increase HP.
It does not filter as well as the stock filter.
It will cause elevated silica levels in the crankcase oil and cause cylinder scoring.
It will cause more frequent fouling of the MAF due to oily dirt passing through the mesh requiring more frequent cleaning of the MAF (something that needs to be done on a stock system, pretty much, never).

I would just go with a TRD CAI. Or if you want the look of your filter showing then go with an AFE filter and not K&N. AFE makes the TRD filter. I have an AFE CAI and I love it. It doesn't give me much better mpg but my truck sounds awesome at higher rpm's and it "feels" quicker at higher rpm's too but idk the facts on that.

Ya... If the filter is over oiled, the oil will coat the MAF.
Once that happens, the fine dust that the filter allows to pass through will stick to it and foul the MAF.

K&N filters were designed for offroad racing. They were not designed to support an engine that is intended to run 300,000 miles and 15 years. They were designed to keep damaging debris out of an engine that is going to be rebuilt every 500-1000 miles.

We've got two issues here. The filter media itself, and the CAI.
The biggest problem with the system, IMHO, is the media.
The CAI, installed properly, will flow well, though it will tend to draw more hot air from under the hood, where the stock intake draws from the fender, which gets it's air from in front of the radiator... it's already a cold air intake.

Benefits? Pretty much zilch.
The OEM filter is less than $20, change it once a year and even that's overkill (it's due every 60k, but offroad driving will foul it more quickly).
